A man in his 40s with ST-segment elevation myocardial infarction complicating cardiogenic shock was transferred to our hospital. Emergent percutaneous coronary intervention for the left anterior descending and left circumflex arteries supported with Impella CP was performed. However, his cardiac function was severely impaired, and anuria developed, necessitating continuous renal replacement therapy (CRRT). After Impella CP was removed on day 6, the patient remained dependent on inotropes and CRRT. Following volume reduction to manage pulmonary congestion, symptoms of low perfusion appeared. Then, Impella 5.5 was inserted on day 38 as a bridge to decision. On day 52, the urine volume reached >2000 mL/day, and CRRT was discontinued. On day 56, the patient was transferred to a certified facility for left ventricular assist device implantation or heart transplantation. This case suggests the potential of Impella 5.5 as a bridge to decision in patients with organ failure caused by low cardiac output.

Diabetes is a growing health concern in developing countries, causing considerable mortality rates. While machine learning (ML) approaches have been widely used to improve early detection and treatment, several studies have shown low classification accuracies due to overfitting, underfitting, and data noise. This research employs parallel and sequential ensemble ML approaches paired with feature selection techniques to boost classification accuracy.

Long-term Mechanical Circulatory Support in Cardiogenic Shock Secondary to Acromegaly. Case report.

Rev Esp Anestesiol Reanim (Engl Ed)

January 2025

Departamento de ECMO, Fundación Cardiovascular de Colombia, Floridablanca, Colombia. Electronic address:

Heart failure is a complication that may develop in patients diagnosed with acromegaly. This complication can progress to cardiogenic shock, which in cases like the one described, may be refractory to optimal medical management, necessitating the use of mechanical circulatory support as a bridge to decision. Given the specific morphology of this patient's heart, the likelihood of finding a suitable donor in our environment was very low.

The Jordan Valley (JV) is a critical region where the interplay of water, energy, food, and ecosystem (WEFE) dynamics presents both challenges and opportunities for sustainable development and climate change mitigation and adaptation. In such a transboundary river basin with acute nexus problems and a long history of conflicts, it is essential that conscious efforts are made to pluralize the debate and actively encourage stakeholders' empowerment, participation and fair collaboration in strategic planning. An integrated framework for participatory strategic planning in the WEFE nexus is proposed, which has been developed in the context of the JV case study.
